Horseshoe crabs are my favorite animal and awsome animals too!, but I have one slight complaint, horseshoe crabs are more closely related to spiders and scorpions than crabs, so I think you should put them under the category miscellaneous. Overall a amazing animal and keep on selling them because I want to buy more of these prehistoric living fossils!

These little guy is great. You don't see him very much.But he keeps the sand bed very clean the tank.

Horseshoe Crabs are a neat addition to any tank. Not only are these dinosaurs cool to look at, they also do a great job of keeping your sand filtered and clean. While it's unfortunate that they don't come out very often when the lights are on, they can be seen from time to time when the lights are off.
